A big tangi is planned for Wiremu Keepa Jnr with preparations well under way for his body to arrive in his home city on Wednesday.
The 23-year-old collapsed and died at his home in Perth on Monday last week.
His Rotorua uncle, also called Wiremu Keepa, said a post-mortem examination had been conducted on his nephew's body but they were still unaware exactly how he died.
"We are still in the dark as to why."
Mr Keepa Jnr was the former head boy at Western Heights High School and was touted as a rising leader for his iwi, Ngati Whakaue.
